if crankshaft is damaged, engine will need to come out.. front diff assembly must be detached from the oil pan, and pan must be removed from engine to remove diff from chassis.
it will give you access to main brgs to inspect for damage.

there are several problems --- one is to check that there is power to the solenoid or relay to engage the starter . Check for good earth wire where it is on the engine /body. If you have power at the solenoid/relay on the wire from the ignition in the run position then it most likely will be a bad solenoid / relay

That stinks... Those engine are more involved. The coolant can leak from three different areas. The head gasket, the cylinder sleeves, and the front timing cover. If you drain the oil pan, drop down the rack and pinion unit and remove the oil pan. You can try pressure testing the coolant and see where the coolant is dripping from. Food for thought. These engines are known for valve issues in the head after 250K miles. The repair alone can be $3K or more. If I can be of anymore help , let me know.

Do you hear the pump come on briefly with key in run, not start? You should check fuel pressure-some parts stores rent a fuel pressure tester for small fee. Or try this: spray some starting fluid into the air intake when trying to start. If it starts and runs a few seconds, you know you have a fueling problem- pump or injectors or something with the fuel.
Always check for trouble codes with a no start. If checking for spark and have no spark to the plugs, then it could be the crank position sensor. That sensor is crucial for the computer to figure spark timing. But if no spark, it could be other things as well, like the cam position sensor, ignition control module, or a problem in the circuits for all these. The crank sensor is just an educated guess for no spark-not a certainty.
Since it won't run, you can't go to have the computer scanned for free at a parts store-do you have any friends or relatives with an OBD-2 hand held scanner? Just to check for any trouble codes, but do check for fuel and spark.

It sounds like it might be as cheap as replacing a fuse or fuses. Have you checked your fuses to see if any of them are blown? Refer to your owner's manual for fuse box location. Fuses can easily be checked with a test light or voltmeter/ohmmeter.

You have the inline 6 engine? You actually have 6 coils. Remove the plastic resonator on top of the engine, remove the ducting to give you more room. When it's off, you now can see all 6 coils. Remove the electrical connector then remove the screw that holds the coil in place. After that, just pull the coil out.

Have your motor mounts and transmission mounts checked. Common problem. Or are you talking about the bump you feel while coming to a stop? Another common problem, grease the slip yoke on the driveline to fix this particular problem.

Sounds like one of your nozzles is clogged to me. Try this.....Get a spray can of air, like the computer air spray. Stick the long air can nozzle into the spray nozzle. Shoot some air back into the system and see if it frees your clog. When my fluid gets low, mine will get gunk in it and clog to the point of not spraying at all. Compressed air usually does the trick. If not, remove and clean or replace the nozzles.

Do the bulbs keep burning out?? There is a recall on this issue, check the recall out. Been there done this.

Should be in your owners manual.
Put the ignition on "run"; push the accelerator to the floor 3 times w/in 5 seconds. The light should blink, after it blinks turn key to "lock" and then turn the truck back on. Light should be off.
